Yes, that’s the point.
Contrary to my sibling’s comment, the point here is that it’s 1 in 5,000 people who get measles despite being vaccinated, which is rather rare. This is why the number jumps so much in the unvaccinated (nothing to do with infants – it’s just that infants are when we normally give this vaccine; the disease usually happens in children and young adults who weren’t vaccinated as infants).
